Who We Are

Our team has extensive experience in the advertising industry, and we feel your pain. We’ve experienced first-hand the late nights of crunching numbers and sorting out messy data. We’ve waited weeks just to get a few simple answers. We watched and wondered: If the way advertising is created and distributed has become so innovative, efficient, and inspiring, why are we still using desktop spreadsheets and systems for planning and reporting?

We knew there had to be a better way.

That’s why we founded ColSpace (short for “Collaboration Space”). Our team is committed to making the media planning process fast, accurate, and accessible.
